If you follow Weight Watchers and you miss bold, restaurant-style dinners that don’t wreck your daily points, these Weight Watchers Zero-Point Shrimp Fajitas are going to change weeknight dinner forever. Imagine sweet, charred bell peppers, thin-sliced red onion caramelized at the edges, and plump shrimp kissed with smoky spices — all roasted together on one sheet pan so the flavors marry and the cleanup is ridiculously easy. The first forkful is bright with lime, smoky with chili powder, and deeply satisfying — and you don’t pay a single WW Point for it. That combination of simplicity and satisfaction is the reason I make this at least once a week.
This is a one-pan dinner that feels indulgent but is built entirely from zero-point ingredients. It’s perfect for nights when you want flavor without fuss, for meal-prep lunches that reheat beautifully, and for anyone who wants to eat well while staying within their WW targets. Read on for the full, detailed recipe, WW strategy, troubleshooting tips, and variations so you can make this your go-to crowd-pleaser.

WW Points Info (required)
- Estimated WW Points per serving: 0 WW Points (when eaten as directed: shrimp + peppers + onions, lightly misted with cooking spray, seasoned with spices and lime).
- Estimated WW Points for whole recipe (4 servings): 0 WW Points
How WW Points were calculated: These are Estimated WW Points based on Weight Watchers principles: shrimp (zero-point lean protein), non-starchy vegetables (bell peppers, onions — zero points), fresh lime, and dry spices. Using oil spray instead of measured oil keeps the dish point-free. If you add tortillas, avocado, cheese, or oil, those add points — see substitution notes below.
My Personal Experience
I’ll never forget the night I turned a tired Tuesday into a little celebration with a sheet pan. I had a bag of shrimp in the freezer and three lonely bell peppers that were pleading not to be wasted. I tossed them with spices, broiled them for a couple of minutes, and suddenly the kitchen smelled like a taqueria. My partner sat down with a forkful and said, “This tastes like we ordered takeout.” I loved that line — because it meant I’d built a low-point dinner that felt indulgent. Since then, this recipe has been my quick dinner for busy nights and my “I want to impress but don’t want stress” meal for friends.
Required Equipment
Large rimmed baking sheet (sheet pan)
A rimmed sheet pan gives vegetables and shrimp room to spread so they roast instead of steam. Use a wide pan — overcrowding traps moisture and ruins the char.
Parchment paper or foil (optional)
Lining the pan speeds cleanup and prevents sticking; parchment maintains better airflow while foil can brown the edges quicker.
Large mixing bowl
For tossing shrimp, peppers, and onions with seasoning evenly — helps you coat ingredients without mess.
Measuring spoons and small bowl
Handy for mixing the spice blend and precise seasoning, which is key to consistent flavor without extra sodium.
Tongs or spatula
To turn the shrimp and vegetables midway so everything browns evenly.
Knife and cutting board
A sharp knife makes quick work of the peppers and onions — even pieces roast at the same time.
Ingredients & Substitutions (with WW effects)
(Makes 4 servings — each numbered ingredient followed by why it matters and WW note)
- 1 lb (450 g) raw large shrimp, peeled and deveined
- Why: Shrimp are the protein star — fast-cooking, naturally low in calories, and high in protein.

Lower-point substitutions and point changes
- Swap shrimp → skinless chicken breast strips: still typically zero points on WW plans, but watch portion size.
- Swap cooking spray → 1 tbsp olive oil: adds approx. 4–6 WW Points for whole recipe (varies by plan). Use spray to remain zero-point.
- Add 1 small avocado (sliced) for creaminess: +4 WW Points (per whole avocado divided by servings).
- Serve with 1 small whole-wheat tortilla: +2 WW Points each.
- Serve with fat-free Greek yogurt (1 tbsp) as a dip: 0 points.
Zero-Point Ingredients: shrimp, bell peppers, red onion, garlic, lime juice, and dry spices are all zero-point when used as directed. That’s how this becomes a true zero-point dinner.
How to Make Weight Watchers Zero-Point Shrimp Fajitas
I break the method into crystal-clear steps and include small tips inside each step so even a beginner can follow without stress.
Step 1 — Prep and dry the shrimp (5 minutes)
Pat the shrimp thoroughly with paper towels — removing surface moisture is the single best trick to ensure they roast and don’t steam. If the shrimp are frozen, fully thaw in the fridge or under cold running water, then dry them well.
Mini-tip: I learned this the hard way — wet shrimp steam and the peppers get soggy. A few extra paper towels here pay off in texture.
Step 2 — Slice vegetables into uniform strips (5–7 minutes)
Trim the peppers, remove seeds, and slice into ¼–½ inch strips. Thinly slice the red onion into similar-width strips so everything cooks at the same speed. Place peppers and onion in a large mixing bowl.
Mini-tip: If you like a little more char, cut slightly thicker pieces; if you want fast-tender veggies, slice them thinner.
Step 3 — Mix the spice blend (1 minute)
In a small bowl, whisk together the chili powder, ground cumin, smoked paprika, onion powder, black pepper, and a pinch of cayenne if using. This is your fajita magic — smoky, warm, and no need for extra salt.
Step 4 — Toss shrimp and veggies with seasoning and lime (2 minutes)
Add the shrimp, minced garlic, and half the lime juice to the bowl with the vegetables. Lightly mist everything with cooking spray, then sprinkle the spice blend over top. Toss gently with tongs or your hands until evenly coated.
Mini-tip: Don’t over-toss — shrimp are delicate and will break if handled roughly.
Step 5 — Spread on sheet pan and roast (10–12 minutes)
Arrange the shrimp and veggies in a single layer on a rimmed baking sheet lined with parchment. Make sure pieces aren’t piled up — overcrowding will steam. Roast at 425°F (220°C) for 8–10 minutes, until the shrimp are pink and opaque and the vegetables are tender with charred edges.
Optional broil: If you want extra char, broil for 1–2 minutes at the end — keep a close eye so nothing burns.
Step 6 — Finish with fresh lime and herbs (1 minute)
Remove from oven and immediately squeeze the remaining lime juice over the pan. Sprinkle chopped cilantro (optional, zero points) and serve.
Mini-Story: I briefly overbaked once — the shrimp tightened up too much. Now I always set a 9-minute alarm and check early. Shrimp go from perfect to tough in a heartbeat.
Air Fryer / Oven / Stovetop Variants (and point notes)
- Sheet pan / Oven (default): Roast at 425°F for 8–10 minutes; broil 1–2 min for char. Remains 0 WW Points when no oil is added.
- Air Fryer: Preheat to 400°F. Cook shrimp and veggies in a single layer; you may need two batches. Air-fry shrimp for 6–7 minutes and veggies for 8–9 minutes, shaking halfway. Air frying can yield slightly crisper edges with same point status.
- Stovetop (sauté): Heat a nonstick skillet, spray lightly with cooking spray, and sauté peppers and onions for 6–8 minutes until tender-crisp. Push veggies to the side and cook shrimp 2–3 minutes per side until pink. This also keeps the recipe at 0 WW Points as long as you use spray instead of measured oil.
Point differences: Using measured oil (1 Tbsp) on the whole recipe adds ~4–6 WW Points, depending on plan. Using oil spray keeps it zero.
Common Mistakes to Avoid
- Crowding the pan: Causes steaming and soggy peppers. Spread ingredients in a single layer for even browning.
- Not drying shrimp: Leads to uneven roasting and watery texture. Pat dry fully.
- Overcooking shrimp: Shrimp cook quickly — pull them as soon as they turn opaque and pink.
- Skipping fresh acid: Lime finishes brighten the dish and cut through spice — don’t skip it.
- Using sugary pre-made sauces: They can add hidden points — keep to fresh lime and spices for zero points.
Pro Tips for Best Results
- Batch roast: If you have a smaller oven or crowding is unavoidable, roast veggies first for 6–8 minutes, then add shrimp for the final 8–10 minutes so both finish perfectly.
- Use large shrimp (16–20 count): They’re easier to cook without overdoing.
- Toast spices quickly: For deeper flavor, toast the spice blend in a dry skillet for 30 seconds before mixing — don’t burn them. Toasting unlocks essential oils and makes flavor pop.
- Finish with acid: Lime juice at the end brightens flavors in a way nothing else can — add a little zest too if you want extra lemon-lime aroma.
- Meal-prep assembly: Roast turkey or shrimp and peppers, divide into containers, add a lime wedge, and refrigerate for up to 3 days. Reheat in microwave or skillet.
WW-Specific Nutrition & Strategy
This recipe is a perfect example of WW-friendly cooking: build meals around zero-point proteins and vegetables and use spices and citrus for flavor rather than fat. Shrimp are lean, high-protein, and filling — your stomach feels satisfied, which helps prevent snack temptation later in the day.
Strategy tips:
- Start your meal with a generous portion of the fajitas, then add a zero-point side (mixed greens or steamed broccoli). That filling protein + fiber combo stabilizes blood sugar and helps you stay within your daily points.
- If you want carbs, add one small tortilla (count the points) or a side of roasted sweet potato (points apply). Planning ahead with those additions ensures you won’t go over your budget.
Variations You Can Try (and how they affect WW Points)
- Chicken Fajitas: Swap shrimp for skinless chicken breast strips — still usually zero points.
- Spicy Chipotle Twist: Add 1 tsp chipotle powder or 1 tbsp adobo (check canned adobo for sugar) — 0 points if just spice; if using sauce, track points.
- Citrus-Herb: Add orange juice (1 tbsp) and chopped mint — 0 points and bright flavor.
- Southwest Bowl: Serve over ½ cup cooked quinoa per serving → +4–5 points.
- Cheesy Finish: Sprinkle 2 tbsp reduced-fat cheddar per serving → +1–2 points.
- Avocado Dream: Add ¼ avocado per serving → +2–3 points.
Always log substitutions in your WW tracker — small swaps add up.
Tips for This Recipe
- Keep a small container of the fajita spice mix in your pantry for lightning-fast prep.
- If you like char, use the broiler briefly but watch carefully.
- For family meals, serve the sheet pan at the table — everyone loves the communal feel and bright colors.
- Use leftover fajita mix in salads or on top of a baked potato (track points accordingly).
Optional Additions
- Low-point salsa or pico de gallo — 0–0.5 points depending on quantity and brand.
- Fat-free Greek yogurt as a cooling dollop — 0 points.
- Light shredded cheese (sparingly) — +1–2 points.
- Warm low-carb tortillas — +2 WW Points each (brand-dependent).
- Pickled red onion for tang (homemade with vinegar) — 0 points.
Serving Ideas
- Zero-Point Bowl: Serve fajitas over a bed of mixed greens; drizzle lime, add cilantro. Zero points and very filling.
- Fajita Lettuce Wraps: Use large romaine leaves as wraps — crunchy and zero points.
- Taco Night: Offer low-point tortillas and let everyone build their own (serve tortillas separately for point control).
- Meal-Prep Lunches: Portion into microwave-safe containers, add lime wedges, and enjoy next-day lunches.
Storage Recommendations
- Fridge: Store in an airtight container up to 3 days. Separate lime wedges for best freshness.
- Freezer: Not recommended for peppers (they get soft), but cooked shrimp can be frozen up to 1 month; thaw overnight and reheat gently.
- Reheating: Reheat in a skillet on medium for best texture (2–3 minutes) — microwave is fine for 60–90 seconds. Reheated shrimp are slightly firmer but still delicious.
Points do not change unless you add new ingredients.
Frequently Asked Questions (FAQ)
1. Can I freeze this recipe?
Yes — you can freeze the cooked shrimp only for up to 1 month (wrap tightly). Veggies don’t freeze well for texture; instead, freeze the shrimp separately and roast fresh vegetables. Freezing and reheating does not change WW Points, but reheating may slightly alter texture.
2. Can I use frozen shrimp?
Absolutely. Thaw completely and pat dry before seasoning. The key is to remove moisture to get roast and char.
3. How can I make this spicier without adding points?
Add crushed red pepper flakes, cayenne, or a sprinkle of chipotle powder — all zero points.
4. Are the fajitas still zero points if I add olive oil?
No — measured oil adds points. A tablespoon of olive oil across the whole recipe usually adds 4–6 WW Points to the batch. Use a light spray to keep it zero.
5. Can kids eat this?
Yes — mild spices please many kids. Reserve a small portion before adding cayenne if you know kids are sensitive to heat.
6. Can I use a gas grill or grill pan?
Yes — toss shrimp and peppers in a grill basket and cook until charred and shrimp are opaque. Grill method keeps it zero points.
7. How long will leftovers stay good?
Store in fridge up to 3 days. Reheat gently in a skillet or microwave for best flavor.
